Open defecation free (ODF) is one of the most important target in Sustainable Development Goals (SDGs) that is intended to break the transmission chain of infectious diseases. This research aims to discover the open defecation (OD) behavior as well as to analyze factors that influence its elimination effort using behavioral change wheel model. This was a cross sectional study involving 210 villagers from Desa Mangunjaya, Bandung during April 2017 who were randomly selected with cluster random sampling method. Data were taken through interview using validated questionnaire, then analyzed using SPSS 20 with chi-square and Spearman rank correlation test. This research found there were 28.6% of residents in Desa Mangunjaya who are still practising OD and 22.4% do not have latrines. There was a significant positive correlation between OD behavior with motivational factor (r = 0.584), capability (r: 0.638), and opportunity (r: 0.548). There was a difference of perception between residents who were still practicing OD and who were not, on what factors are considered to inhibit the ownership and use of latrines. Although both placed the cost factor as the main barrier, residents who practicing OD tend to assess the location of the village as the second greatest obstacle, meanwhile the second group put the lack of education as a major factor in addition to cost constraints. The achievement of ODF condition in Desa Mangunjaya was inhibited by motivational, capability, and opportunity factors. Increasing latrines ownership and knowledge among villagers were very crucial, since they are the most important determinants.
